Bug 118285

Try to remove all module options for snd-opl3sa2 except for index=0.

I tried that. Now I have:

# cat /etc/modprobe.d/sound
options snd-opl3sa2 index=0
# :Yamaha OPL3-SA23
alias snd-card-0 snd-opl3sa2

The problem is still there, when waking up from hibernate.

Also I didn't mention it in the original bug report, but before seeing the I/O
error message (I'm using mpg321 command line tool), I can hear a ratchetting
sound, so I suppose that some low level access are going out to the audio chip.

OK, then it's a bug of the driver.

Please try to reload the driver after resume, and check whether it works.
If it works, we'll have a hope to fix it :)

But, I'd like to work on this problem rather on ALSA bugtracking.  SUSE/Novell
doesn't "support" this driver officially (see "tainted" kernel message).

I tried the rmmod/modprobe ... Might not be a difficult `Oops' to track down,
but it's very likely closely tied to the Tecra8000 hardware idiosyncrasies. As
the Yast2 menus I used at first to configure the sound chip don't even know
about the Hardware addresses used on that laptop, maybe the driver makes a few
assumptions.

snd_opl3sa2: module not supported by Novell, setting U taint flag.

The Oops at removing the module was already fixed in the recent version.
Try kernel-of-the-day (KOTD) from ftp.suse.com/pub/people/mantel/kotd.

I don't have access to this laptop for the time being. As soon as I get a chance
to try, I'll keep you posted. Thanks for your support !!! 

I got the laptop back and I re-installed the final 10.0. The problem no longer
shows up :-)
I suppose that you can close that bug...

Thanks for your support !!!

Fixed in GM-10.0
